I just got a DSTWO and I'm having a bit of an annoying time with it. Immediately when I got it, I was having issues getting it to detect on my DS Lite or 3DS, so I made sure to download the latest kernel and the latest firmware, but that hasn't helped. On my DS Lite I have Auto Mode turned on, and it can take 5 or 6 reboots before my DSTWO is detected and boots into the flash cards firmware. I have tried multiple different micro SD cards and none of them seem to make a difference, and one of them is from my Gateway blue card (r4i clone?) Which works without any issues. Any ideas on this? The person I bought it from said that it worked every time for them on their DS and 3DS. I also have no issues with any other flash cards on my DS or 3DS, and I am nor sure if it's a contacts issue on the DSTWO side because it will work after several reboots even if I don't reseat the cartridge or anything.
